A DESCRIPTION OF THE PROBLEM :
Listeners on tableView.getSelectionModel().getSelectedItems() are not notified, when the selection changes because an element was removed.

this works if the selectionMode is SINGLE, but not if it's MULTIPLE

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
run the sample application, select the first row "A" and press the "remove first" button.
check console output.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Listeners on tableView.getSelectionModel().getSelectedItems() are notified
ACTUAL -
Listeners on tableView.getSelectionModel().getSelectedItems() are NOT notified
